Alain22 The first post was actually in English, so translation did work.
As to rotation - we already have this feature. You can rotate several image types including JPEG, and that does not involve editing file, only updating its metadata. That is why this operation is completely safe and does not deteriorate your image quality unlike any editing and subsequent compression to JPEG.
Anyway, as you know we are listening to our users and if there will be huge demand - we can add some basic editing like it was in Picasa.
